Strange demons created by the Ended Deities to kill at random. They were trapped by the Olympians in another dimension soon after the fall of the Titans, but a rift in Cardiff somehow allowed them to escape. They are scarce, and wander the Earth seeking for specific targets of importance.

An Emissary of Death. These things are known by Wizards to truly exist; whether they are the Calling Wraiths is not known.

Death itself upon the Throne.

Messengers sent by Death to extinguish those that were supposed to die but somehow didn't, they also serve a role as couriers for Death, sending messages to other supernatural beings, such as the Queen of Elves, the Fang of the Dragon Clan, the Archmage of the Wizard order, Love, and the minor deities. Their role in destroying specific targets would only be known to Death, and he's not telling.
